Tyvek® Metallised Tape is made of durable metallised Tyvek® HDPE and acrylic adhesive for strong, durable bonds. It is a single-sided waterproof tape that is ideal for sealing overlaps of Tyvek® Reflex and AirGuard® Reflective AVCLs. It is also suitable to seal around penetrations, pipework, windows and doors. This tape is compatible with metallised Tyvek® and AirGuard® membranes to maintain the low emissivity of the membrane surface.
